Plasterer s hoe



'UNITED STATES PATENT OFFICE.

PATRICK O. OANFIELD, OF ASHTABULA, OHIO.

PLASTERERS HOE.

SPECIFICATION forming part of Letters Patent No.3l7,502. dated May 12, 1885.

(No model.)

Be it known that I, PATRICK C. UANFIELD,

a citizen of the United States, residing at Ashtabula, inthe county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Plasterers Hoes; and I do declare the following' to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reterence being had to the accompanying drawings, and to the letters and iigures ot'reference marked thereon, which -form apart of this specifica-tion.

This invention has reference to an improvement in hoes, more especially such as are used by plasterers, having for its object to eit'ect the thorough mixing ot' the mortar by comminution, the intimate intermixtureot' the substances being thus eit'ected; and the invention consists ofthe detailed construction ot' the blade, substantially as hereinafter more fully described and claimed.

In the accompanying drawings, Figures l V and 2 are a front and a rear view,respectively,

of my invention. ot' the same.

Similar letters of reference in lthe several drawings denote like parts.

In the embodiment ot` my invention I coustruct the blade A in all respects, except as hereinafter pointed out,of the usual construction. 'lhe tang is made integral with the blade, forming a tapering thickened-up central portion or rib, b, upon the rear side ot' the blade, said rib extendin gfrom a little belowthe middle of the blade upward and over the top edge of the blade, thereby reentorcing the blade where the greatest strength is needed, and to compensate for the weakening of other parts arising from the further construction of the blade, as will be presently described.

Fig. 3 is a perspective View It is a wellknown fact that upon bringing an iniierible or un yielding substance into forcible contact with a yielding substance, or one incapable ot' resisting the blow or force ot' the other, should the first present a broken or perforated surface to the latter, the particles of said latter substance will be forced through the apertures or perforations of said former substance, whereby the unresisting material or substance will be divided up orcomminuted, and the same be more thoroughly acted upon, thereby securing the best possible results. Vith this end in view I have provided the blade A with apertures or perforations O O, one `being disposed upon each side of a vertical plane passing through the rib or thickened portion forming an extension of the tang. In addition to this result, it greatly facilitates and lessens the labor ot` thoroughly working up and mixing of the'mortar.

I am aware that it is not new to make a weeding-hoe with an opening in the center ot' the blade to prevent earth from adhering thereto.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

The hoe-blade A, having its central portion refenforced by a rib, b, a continuation ot' the tang, and provided with perforations or apertures O C, one arranged upon each side of a vertical plane passing through said rib or thickened portion of the blade, substantially as shown, and ior the purpose set forth.

In testimony whereof I attix my signature in presence ot two witnesses.

PATRICK C. GANFIELD.
